A region of the navigation map. A region of the navigation map. It tells the [NavigationServer3D] what can be navigated and what cannot, based on its [NavigationMesh] resource. Two regions can be connected to each other if they share a similar edge. You can set the minimum distance between two vertices required to connect two edges by using [method NavigationServer3D.map_set_edge_connection_margin]. Bakes the [NavigationMesh]. The baking is done in a separate thread because navigation baking is not a cheap operation. This can be done at runtime. When it is completed, it automatically sets the new [NavigationMesh]. Determines if the [NavigationRegion3D] is enabled or disabled. A bitfield determining all layers the region belongs to. These layers can be checked upon when requesting a path with [method NavigationServer3D.map_get_path]. The [NavigationMesh] resource to use. Notifies when the navigation mesh bake operation is completed. Notifies when the [NavigationMesh] has changed.
